I don't believe concealed carry, and especially open carry, are necessary. But if you insist on doing it all I ask is you be mindful of all those around you and participate in vigorous gun use and safety training equal to what law enforcement officers go through. An LE spoke to our church some time ago about safety. She said you need to be so well trained that you use the weapon instinctively. That requires refresher training every few weeks or months, just as the LE folks do. When you are in a panic or crisis situation you dare not plan on being able to think rationally and quickly. The human mind isn't created that way.
